PL Series actuators which are designed for use on rising stem globe control valves, provide up to 4400 lbs. They have (19,600N ) of force and up to 3.9” (100 mm) travel – much greater than other competitive electric linear actuators. This increased up and down force allows use of a globe valve for increased flow control in higher pipe diameters with higher close off pressures versus use of a corresponding butterfly valve with less flow control and lower close-off pressures. There are a range of advantages to this series with key features including; Field Selectable Travel Stops – travel stops can be set by location within the stroke or by the rated force at the end of the stroke. • On/Off/Floating/Proportional Control – precision proportional control is achieved through an improved microcontroller that has 4-20mA or 2-10VDC input and feedback, AutoCalibration, and flashing LED diagnostic indicators. • Customizable Mounting System – a PEI-designed linkage system that is easily configured to various valve bonnets and stem heights. • Manual Override – a standard disengagable manual override that allows fast and simple manual positioning of the valve. • Standard Voltages – actuators are compatible with 24VAC, 24VDC, 120VAC, and 230VAC power supplies.
